My heating unit is around 10 years old. For the last couple of seasons, the inducer fan has made a little noise, but as soon as the flame lights, the noise went away. Now it makes a noise sometimes like a bunch of crickets while it is running and doesn't stop until it spins down.
How much time should I let this go or should I have it replaced soon?
